Steven Pritchard · Follow 2 min read · -- What Inspired Synthsara? In a world where power is concentrated in the hands of a few, and technology is used more to control than to liberate, the need for change is undeniable. Synthsara was born from this necessity—a vision for a new era where technology serves humanity, rather than enslaving it.

I recently moved a bunch of libvirt VMs from a CentOS 7 host to a CentOS Stream 9 host. Normally moving virtual machines from one libvirt host to another is pretty easy. All you need to do is stop the VM on the original host, copy the disk image from host to host (with rsync or whatever is convenient), dump the VM config (with virsh dumpxml guest), and import that config on the new host (with virsh define). It turns out a few things have changed that make that not quite work though...

In August of 2016, I lost a (relatively) large (for me at the time) ZFS array. Rather than tell you how it happened to me, watch how it happened to Linus Tech Tips. My story is almost identical, except the array in question was much smaller, but to make matters worse it was mostly cobbled together with old hardware, including drives, so when the array died, there were a lot of bad drives. My array started life as 15 750GB drives in a RAID-Z2.
